Y9 N[ UW Comments(Additional pages may be added as necessary)

Status control stantion has minimal self-weight, a weighted base with a low center of gravity, and are interconnected.

Therefore, any potential impacts from the stantion during a seismic event would be insignificant and would not cause damage or imapir the function of the MCC. In addition, chatter is not a concern with breakers.

This assesment is in agreement with conclusions drawn in seismic house keeping procedure PMP-5020-RTM-001.Walkdown performed on 4/7/2013.Evaluated by: Tyler Blossei Date: 6/26/2013 Lindsay Yates *6/26/2013 C-806 DC Cook Unit I & Unit 2 SD-121023-001 Rev. 2, 01/13/14 Status: YZ N[-- U[-Seismic Walkdown Checklist (SWC)Equipment ID No. 1-11B Equip.
